[asterisk-ss7] ringback problem

[dave george]

One of my customer is not getting any ringback from me.  He is sending sip
to my asterisk ss7 box using libss7 with TE410P card.

I tried the various option (yes, no and never) for progressinband in the sip
profile and none worked.

Customer is using genband SBC

The customer wants:

100 trying
180 ringing with SDP

Or 

100 trying
183 with SDP



And asterisk is sending:

100 trying
180 ringing 
183 with  SDP

This is how we dial the extension

[wholesale]
exten => _473.,1,Dial(DAHDI/g1/${EXTEN})
exten => _473.,n,Hangup


customer profile

[customer1]
type=peer
context=wholesale
host=x.x.x.x
nat=no
canreinvite=no
progressinband=yes
dtmfmode=rfc2833
insecure=port
disallow=all
allow=g729


Thanks,
